1. 1. Investigation of Modified Cellulose and Starch via Hydrolysis and Mass Spectrometry

   Författare :Arieh Cohen; Avdelningen för arbets- och miljömedicin; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ESI-MS; Polysaccharides; Hydrolysis; Cellulases; Starch Hydrolases; Enzymatic Degradation; Enzymes; Substituent Distribution; Modified Cellulose; Mass Spectrometry; Modified Starch; Analytical chemistry; Analytisk kemi; HPAEC-PAD;

   Sammanfattning : Starches and celluloses can be chemically modified in order to affect their physiochemical properties. Modification of these carbohydrate polymers entails derivatising their free hydroxyl groups with functional groups. LÄS MER

3. 2. Development of Transgenic Potatoes to Attain Novel Starch Qualities

   Författare :Mariette Andersson; Tillämpad biokemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Livsmedelsteknik; Food and drink technology; Biokemisk teknik; Biochemical technology; StGH; starch yield; RNAi; antisense; gene silencing; ahas; potato transformation; sbe2; sbe1; gbss; amylopectin; amylose; Starch; potato;

   Sammanfattning : Starch is a plant-derived polysaccharide with many uses in different food and non-food applications. In this thesis, the production of two novel potato starch qualities, amylopectin and high-amylose, and the modifications and the characteristics of the produced plants and starches are described.

4. 3. Modified Starches in aqueous and plastisol coating

   Författare :Agneta Jansson; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Starch; Polyvinyl alcohol; Water vapor barrier; Tensile properties; Rheology; Chemical Engineering; Kemiteknik;

   Sammanfattning : The interest for coatings containing renewable materials has enlarged in the last decade. Materials from the nature are investigated like starch, cellulose derivatives, protein (gelatin), chitosane by many. In this study potato starch has been used. LÄS MER

5. 4. Agro-Waste Derived Additives for Polylactide and Tapioca Starch

   Författare :Edwin Azwar; Minna Hakkarainen; Anna Wistrand; Christian Glandfils; KTH; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Agro-industrial waste; wood flour; rice bran; polylactide; starch; biomass; degradation; SRA - E-vetenskap SeRC ; SRA - E-Science SeRC ;

   Sammanfattning : Development of materials from renewable resources is one of the big challenges facing our world. In this thesis agro-industrial waste derivatives were developed and evaluated as additives for two common renewable polymer matrices, polylactide (PLA) and starch. Two waste products, wood flour (WF) and rice bran (RB) were evaluated in different forms. LÄS MER

7. 5. Interactions between Amylose, Native Potato, Hydrophobically Modified Potato and High Amylopectin Potato Starches

   Författare :Fernando Ortega-Ojeda; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; DSC; rheology; starch; polymers;

   Sammanfattning : The behaviour of different starches and their mixtures was investigated using several analysis techniques, i.e. small-deformation oscillatory measurements (rheological measurements), differential scanning calo-rimetry (DSC), light microscopy, and UV spectrophotometry (turbidi-metry).
